This is already its scientific name. There is no other name for it accept for the definition.
Plants belong to the Kingdom Plantae. A scientific name for Plants is called "Plantae".
the non vascular or vascular flower
The plant kingdom is divided into several phyla, with the two main phyla being Angiosperms (flowering plants) and Gymnosperms (non-flowering plants like conifers). Angiosperms are the most diverse and widespread group, while Gymnosperms include plants like pines, spruces, and firs.
A non-living thing does not have a scientific name because scientific names are used to classify and describe living organisms based on their characteristics and relationships. Scientific names are given to species, genera, families, and other taxonomic categories within the living world.
germs
Conifers are non-flowering plants.
Gymnosperms - 'naked seed'. But that does not include mosses, which are plants, but do not have true seeds. Ferns are vascular plants, but don't have seeds either.
Flowering plants require pollinatio non-flowering plants do not.
flowering plants and non-flowering plants
You get both flowering plants and non-flowering plants; non-flowering are things like mosses, ferns and liverworts which produce spore, flowering plants produce seeds
bird's nest fern staghorn fern anyway, all ferns are non-flowering
Plants are classified as flowering(angiosperms) or non flowering(gymnosperms).
All flowering plants flower to attract pollinators to help to produce either fruit or seeds, so your question is difficult to give an answer to. If you can be a bit more specific I'll try to help.
Non-flowering plants are separated from flowering plants at the division level in the taxonomic scheme. Non-flowering plants belong to the divisions like Bryophyta (mosses), Hepatophyta (liverworts), and Pteridophyta (ferns), while flowering plants belong to the division Magnoliophyta (angiosperms).
It is a flowering plant
There's no mystery here. Non-flowering plants don't have flowers.
